利用透射电子显微术,研究了Zr55Al10Ni5Cu30块状非晶室温单轴压缩断裂后样品微观结构变化特征.实验观察到由于塑性形变的集中导致的局部区域内自由体积增加现象,表明局部自由体积增加主导着非晶合金的形变行为.
The microstructure of Zr55Al10Ni5Cu30 bulk amorphous uniaxial compression fracture was investigated by transmission electron microscopy. The experimental results show that the increase of free volume in the local area due to the concentration of plastic deformation indicates that the increase of local free volume The deformation behavior of amorphous alloys.
